✦ Synopsis
Given a measurable space X, F F , a fuzzy measure on X, F F , and a nonnegative function f on X that is measurable with respect to F F, we can define a new set Ž . function on X, F F by the fuzzy integral. It is known that is a lower Ž . semicontinuous fuzzy measure on X, F F and, moreover, if is finite, then is a finite fuzzy measure as well. In this paper, we generalize in several different ways the concept of absolute continuity of set functions, as defined in classical measure theory. In addition, we investigate the relationship among these generalizations by using the structural characteristics of set functions such as null-additivity and autocontinuity, and determine which types of absolute continuity of fuzzy measures Ž . are possessed by the fuzzy measure or the lower semicontinuous fuzzy measure obtained by the fuzzy integral.
